It was supposed to be simple. The local DIY shop has closed, so I thought I'd go to B & Q. I wasn't quite sure where it was, so I looked on line. Armed with a postcode, road name and sat nav, I set off. First problem: sat nav didn't like the combination of postcode and road name. So I went on just the postcode. When I arrived at a residential street, I assumed I'd written down the directions wrongly. As I don't have a phone that accesses the net, I texted home to check. I was looking for the right place. Second attempt: Tried just the road name. Ended up on another road that was still not right. Third attempt: Tried a partial postcode plus correct road name. Eventually ended up at right place having gone wrong way down road to start with (thanks sat nav!). Decided it was best to lock sat nav in boot and make my own way home. Did not get lost/go wrong way once.
